Just a little shoot out for say some state i experienced...

When you use x11vnc server on your tablet for control and see your tablet on your desktop, you ave some issue when you try click on some area on the desktop...

Yes in fact, in x11vnc server, whit default installation....you got a lot of issue...

in fact this 3 files you need to install for drag lock here

this 3 files fix this x11vnc in the same time...

i dont know why...but after i installed this 3 files for drag lock option first, i realise my x11vnc its completely worked now...so if you have an issue whit you x11vnc...try to install this 3 files woot
